How to Use gqlgen for GraphQL in Go

Use the graphql package from weaviate-go-client to construct queries via a fluent builder pattern. Initialize the client, then chain methods like Get(), WithNearVector(), and Do() to execute the query.

import (
	"github.com/weaviate/weaviate-go-client/v4/weaviate"
	"github.com/weaviate/weaviate-go-client/v4/weaviate/graphql"
)

// Assuming wvClient is initialized and vector is available
result, err := wvClient.GraphQL().Get().
	WithNearVector(graphql.NearVectorArgBuilder().WithVector(vector)).
	WithClassName("Document").
	WithFields(graphql.Field{Name: "text"}).
	WithLimit(3).
	Do(ctx)

Using gqlgen for GraphQL in Go lets you ask the Weaviate database for specific data without writing raw text queries. Instead, you use a series of commands that build the request step-by-step. It works like filling out a structured form where each line adds a specific rule for what data you want to retrieve.
